St John Youth in New Zealand is a cadet-based programme designed for children and young people aged between 6 and 18. Members who turn 18 tend to remain in St John Youth in leadership roles. St John Youth is closely affiliated with the Order of St John in New Zealand, of which Her Excellency the Queen Elizabeth II is the sovereign head. St John Youth is divided into two programmes. There is the Penguin Programme for children aged between 6 and 8, while the Cadet Programme for young people aged from 8 to 18. While the basis for St John Youth is first aid, other topics like drill (marching), healthcare and leadership make up major parts of the St John Youth programme.
